Century Motors 452B Motor

The Century Motors 452B is a versatile 42 frame, 1/20-1/50 HP multi-horsepower motor designed for demanding fan coil and room air conditioning applications. Engineered as a permanent split capacitor (PSC) motor, this unit features a 3/8" diameter dual shaft with a 10.125-inch extension on each side, making it an ideal double shaft blower motor for dual-wheel configurations. Operating at 115V with a 1075 RPM rated speed across 4 speeds, it allows for precise airflow tuning in various HVAC setups. The open air over (OAO) enclosure and sleeve bearings ensure reliable continuous duty performance when positioned within the system's airflow. This HVAC fan coil motor utilizes a resilient base mounting to minimize vibration transfer. It serves as a direct replacement motor for Carrier HC25ZN362 and HC27ZN042, providing a drop-in solution for contractors servicing legacy equipment.

Key Benefits

• Multi-HP Versatility: High-efficiency design covers 1/20, 1/25, 1/35, and 1/50 HP ratings, reducing the need for multiple truck stock items.
• Flexible Speed Control: 4-speed taps allow for optimized CFM delivery to match specific system requirements.
• Extended Dual Shafts: Features 3/8" x 10-1/8" shafts on both ends, compatible with most dual-wheel fan coil units.
• Thermal Protection: Internal automatic reset thermal overload protection prevents winding failure during restricted airflow conditions.
• Simplified Installation: Includes a 6 MFD 370V capacitor and identifies as a CW lead end rotation model for quick field integration.

Common Questions What are the primary replacement cross-references for the Century 452B? The 452B is the primary aftermarket replacement for Carrier/BDP HC25ZN362 and HC27ZN042, as well as several Fasco and GE 5KCP29 series motors. Does this motor include the necessary run capacitor? Yes, this PSC fan motor comes with the required 6 MFD at 370 VAC capacitor to ensure proper startup torque and operational efficiency. Can the 452B motor be used in totally enclosed applications? No, the OAO (Open Air Over) rating requires the motor to be mounted in the path of the fan's discharge or intake air to maintain safe operating temperatures.
